Manufacturing Process of SUS310S Stainless Steel

The manufacturing process of SUS310S typically involves:

1. Melting raw materials in an electric furnace
2. Refining the molten metal
3. Continuous casting into slabs
4. Hot rolling to reduce thickness
5. Cold rolling to achieve final dimensions
6. Solution annealing at 1100-1150°C followed by rapid cooling

Comparison of SUS310S with Other Stainless Steel Grades

SUS310S offers superior oxidation resistance and high-temperature strength compared to other austenitic grades.

Heat Treatment and Corrosion Resistance of SUS310S

SUS310S exhibits excellent corrosion resistance in high-temperature environments:

• Resists oxidation up to 1150°C in continuous service
• Suitable for intermittent service up to 1040°C
• Resistant to carburization and reducing environments

Heat treatment:

• Solution annealing: 1100-1150°C, followed by rapid cooling
• Stress relief annealing may be performed at lower temperatures
